Get going with tidymodels, a collection of R packages for
modeling and machine learning. Whether you're just starting out or have
years of experience with modeling, this practical introduction shows
data analysts, business analysts, and data scientists how the tidymodels
framework offers a consistent, flexible approach for your work.
RStudio
engineers Max Kuhn and Julia Silge demonstrate ways to create models by
focusing on an R dialect called the tidyverse. Software that adopts
tidyverse principles shares both a high-level design philosophy and
low-level grammar and data structures, so learning one piece of the
ecosystem makes it easier to learn the next. You'll understand why the
tidymodels framework has been built to be used by a broad range of
people.
With this book, you will:
• Learn the steps necessary to build a model from beginning to end
• Understand how to use different modeling and feature engineering approaches fluently
• Examine the options for avoiding common pitfalls of modeling, such as overfitting
• Learn practical methods to prepare your data for modeling
• Tune models for optimal performance
• Use good statistical practices to compare, evaluate, and choose among models
